Patent 301/1213; Holland, March 24, 1921,k

Patent 11,255; Belgium, March 31, 1921, Patent 295,263; Czechoslovakia,March 29, 1921, application P. 2307/21), of which the following is aspecification. Y

This invention Y relates to la-ce braiding machines of the kind in whichthere is one bobbin for each driver, i. e. to so-called single threadlace braiding machines.

The invention deals with the longknown problem of producing machineswhose carriers are arranged to turn to the right and l left and whosedrivers are arranged in a circle or similarly. This problem is solved byassociating special guide members with the arrangement that renders itpossible to turn the drivers to the right or left. These guide membersare-made to move into and away from the carrier track and when they aremoved in they .prevent the carriers from leaving the driver on whichthey are to travel. The specic manner of accomplishing this inaccordance with the invention consists in certain guide members which,in conjunction lwith the neighbouring drivers, form circular tracks,being moved out of the planes of the feet of the carriers when thecarrier drivers are brought into engagement with the driving gear by`which they are rotated vto the right or left. The said guide membersfor two neighbouring drivers may be combined in one piece and the edgesot the guiding portions of the guide members and of thefeet of thecarriers may be bevelled.

Arrangements are also made by which the i coupling members which giverise to right hand or left hand motion can only be thrown out 'of gearat the moment the particular driver has completed the desired rotationeven though the jacquard mechanism may have previously ceased to exertits pull. The coupling of the driver with the various rotating drivingwheels may be effected in one and the same direction by means ofjacquard apparatus, and the guide member may be arranged to beindirectly moved out of thetrack of the carriers whenever one of the twojacquard pulls operates.

Another feature of the invention consists in one of the driving wheelsfor operating the driver being mounted on a special sleeve whichprevents the driving wheel from imparting undesired rotation to thedriver. The sleeves may be attached lto small standards which also haveparts that maintain the coupling in its position of engagement until thedriver has reached its proper vposition.

A constructional form of the invention is. shown'in the drawing in whichFig. 1 isa section through a driver associated with itsv coupling andholding devices and adapted to be rotated to the right and left.

F'ig. 2 is a sidey view of Fig. 1 observed in the direction of thearrow.

Fig.v 3 is a plan view of the track plate.

Fig. 4 is an elevation of the assembled machine with all itsaccessories. i

Fig. 5 is a plan view of the machine according to Fig. 4 showing thedirection of movement of the driving wheels.

Figs. 6 and 7 show diiierent ways of ,driving ythe toothed wheelsarranged to be brought into gear with the drivers.

Fig. 8 is a perspective view of a movable guide member.

Y The drivers 1 of the machine are located in the track plate 2 and haverecesses each of which has two driving edges 3. 'Each driver 1 isrigidly connected or integral with a sleeve 4 associated with couplingmembers 5 and 6 adapted to move up and down on the sleeve whilst beingprevented from r0- tating around the same., To this end the sleeve 4 ismade with corners as shown in Fig. 3. The coupling member 5 is adaptedto engage with the clutch of the toothed wheel 7 and the coupling member6 is arev CITI wheel 8 so that the driver 1 is rotated in differentdirections according as the coupling member 5 or 6 is thrown into gearwith its corresponding toothed wheel 7 or 8 respectively.

The coupling member 5 (Figs. 1 and is in 'engagement with a forli E)which has a sleeve-shaped portion 92l that is lined by a screw to thero( l() so that, on a downward pull being exerted on this rod by meansot the jacquard apparatus, the coupling inembcr is inoved'by the torl;i) into engagement with the toothed wheel 7. After the tori; i hastravelled downward a certain distance its sleeve strikes against thelateral projection 11 ot a sleeve 12 which is adapted to move up anddown and has a plate 13 (Fig. with an upwardly extending` proj ection14s. This projection 1l is adapted to enter into the notches 17 in adisk 15 lined by screws 16 1) to the driver 1. lllhen the projection 1lenters a notch 1l' the driver 1 is prevented from executing an undesiredrotary movement aio'und .its axis.

The sleeve 12 is arranged to move up and down on the rods 18 and 10.

Arranged at the right ot Fig. 1 is a standard 19? provided withprojections 2O and 21 that protrude into recesses and 23 in the couplingmembers 5 and (l respectively, and which permit or downward niovement ofthe ,coupling members and (i when the said recesses are located abovethe projections 20 and 21.

By the pull exerted by means of the jacquard apparatus on the rod thecoupling nieinber 5 is lirst movedl down until the prejection has passedthrough the recess or notch 2O in the upper annular ridge ot thecoupling member and then the sleeve 9a ot the tori; strikes against thelocated projection 11 of the sleeve 1:2 and at the saine time the teethot the coupling member 5 come into enga-gement with the clutch ot thetoothed wheel 7` and the upwardly extending projection 14 leaves thecavity 1i' and the guide member 13 moves out ot' the path ot the toot 33ot the carrier.

i'lhen the pull exerted by means oi? the jacquard apparatus ceases thecoupling member 5 is retained in its position of engagement by theprojection 2O until one ot the notches :22 appears beneath the saidprojection, when the spring 24 will be able to push the rod 10 with thearm 9, and theretore the coupling` member 5 upwards.

The rod 10 is provided with a pin 25 to enable it to be operated by thespring The `lateral projection or arm 11 ot" the sleeve 1Q and the plate13 with the projection 111 are pushed upwards by a spring 26 when thepull exerted by the jacquard apparatus ceases.

The engagement oit the coupling member 6 with its correspondingl clutchis eitected by a forked arm 28 projecting` trom a sleeve 2T lined by ascrew' to the rod 18. llfhen a pull exerted on the rod 18 by means otthe jacquard apparatus the part 12 is moved downward by a collar 99after the projection 21 has passed through the notch in the upperannular ridge ot the coupling member (i. At the saine time theprojection 1st is moved downward so as to leave the corresponding recess17 in the disk 15.

When the puil exerted by means ot the jacrpiared apparatus ceases thepaits 2i, 21% and the coupling meniber 6 are moved upward by a spring 30and restored to their normal positions as soon as the notch l appearsbeneath the projection 21. 1n this case also the part 12 is restored toits normal position by the spring 25.

As will be seen from Fig. 1 the toothed wheel 'l is arranged on a sleeve51 supported b v the pillar 1S). By this arrangement the toothed wheeli' is prevented troni imparting undesired rotary motion to the driverwhich might happen it' the toothed wheel T were directly journalledonthe pillar.

in addition to the upwardly extending projections 1d the parts 13, Fig.rave curved portions 32 which, in conjunction with their neighboringdisk, torni a coniplete circular track when the plate 153 is in itsraised position. lt is thus seen that when the plate 13 is drawn downthe carriers are enabled to rotate upon the driver corresgondinp` to thesaid .downwardly niovef. plate whilst their access t0 the neighbouringdriver is prevented by the cnrved portions 32 ot the neighbouring plateson account ot these curved portions still being in their rainedpositions. rhe curved parts 32 arel preferably bevelled so that thecarriers will, it necessary, slide oil' these parts when the plate 123is raised and move in between two neighboring plates 13. rlfhe toot Fig.il, ot the carrier may be made conical tov the same purpose.

In Fig. 4, 34 is a belt pulley by which the machine is driven. rThispulley rotates a gear wheel 5) which drivrs a large toothed wheel 36 bywhich toothed wheels 37D, SlT are rotated. The toothed wheel 37tansniits its motion to a set et lower wheels (Figs. 5 and whilst thetoothed Wheel 37* imparts its motion to a set ot upper wheels T (Figs. 5and 7). By this means the upper wheels ot' each driver are rotated inthe opposite direction to the wheels ot the lower di ivers.
